1 Claim.

My invention relates to nose pad construction for eye-glasses and has reference more particularly to the coupling of the pad proper with the supporting arm therefor.

The object of the invention is to provide a simple and inexpensive mounting that requires no special tools for coupling the pad to the supporting arm.

Another object of the invention is toprovide a pad mounting which will have proper play or rocking movement on the arm without danger of separation between the pad and the supporting arm for same.

With this and other objects in view, the invention consists of certain novel features of construction which will be particularly pointed out in the appended claim.

In the accompanying drawing,

Figure 1 is a vertical section through a nose pad mounting embodying my invention.

Figure 2 is a section on line 2-2, Figure 1 and Figure 3 is the elevation of the end of the supporting arm for the pad before it is connected to the pad.

Referring to the drawing, *5 is a metallic plate which is imbedded into the plastic material 6 shaped to form the pad, and a lug I forming an integral part of the plate 5, projects through the plastic material on the rear face of the pad.

The lug I has an aperture 8, running transversely of the longitudinal axis of the pad and substantially parallel to the faces thereof.

A supporting arm 9 has its free end- It enlarged, and in the enlarged part, an orifice II of substantially rectangular shape is formed to receive therethrough the lug I of the pad.

The orifice II of the arm 9 has trunnions I2 disposed on the longer sides of the orifice II. These trunnions I2 are adapted to enter the aperture 8 in the lug I from the opposite end of said aperture 8 when outer sides I3 of the enlarged portion III of the arm 9 are squeezed while the lug I is located in said orifice II.

It would therefore be apparent that the distance between the trunnions I2 in the orifice II are sufiiciently apart to permit the lug I topass into the orifice II, in consequence when the enlarged par-t Ill of the arm 9 is squeezed, as previously stated, the trunnions serve as pivots for the pad on the arm 9, in addition, preventing the pad from being separated from the supporting arm while permitting the pad to oscillate on the trunnions as an axis.

It is evident that in the manufacture of the arm 9 the orifice II formed in the enlarged part III of the arm has the distance between the trunnions I2 sufiiciently apart to permit the lug 1 of the pad to pass through the orifice I I. The relation between the lug I of the pad and the supporting arm engaging it is such that the trunnions I2 and the aperture 8 are in a substantial alignment, and the mere pressing of the sides I3 of the enlarged portion ll] of the arm 9 brings the trunnions I2 into the aperture 8.

The material used for the arm 9 is sufficiently pliable to perform the operation described and to permit the adjustment of said arm with the pad for difierent types of eye-glass mountings.

The orifice II, with the trunnions I2 therein, presents in its peripheral outline the outline of the capital letter H disposed transversely of the arms length.

I claim:

A nose pad unit comprising, a pad having an apertured lug on the rear face thereof, a supporting arm terminating with an orifice in the shape outling the capital letter H, which is disposed transversely of the arm length, said orifice being adapted to receive the lug, the portion of the orifice outlining the transverse part of the letter constituting trunnions adaped to align with the aperture of the lug when the same is inserted into the orifice, said trunnions being adapted to enter the aperture of the lug when the sides of the said letter are forced toward each other, whereby said lug is mounted to rock on said trunnions in said arm.
